On LoongArch system, there is iocsr address space simliar system io address space on x86. And each cpu has its separate iocsr address space now, with this patch, iocsr address space is changed with per-board, and MemTxAttrs.requester_id is used to differentiate cpu cores.
Bibo Mao (2): hw/intc/loongarch_ipi: Use MemTxAttrs interface for ipi ops hw/loongarch/virt: Set iocsr address space per-board rather percpu hw/intc/loongarch_extioi.c | 3 - hw/intc/loongarch_ipi.c | 184 ++++++++++++++++++----------- hw/loongarch/virt.c | 88 ++++++++++---- include/hw/intc/loongarch_extioi.h | 1 - include/hw/intc/loongarch_ipi.h | 3 +- include/hw/loongarch/virt.h | 3 + target/loongarch/cpu.c | 48 -------- target/loongarch/cpu.h | 4 +- target/loongarch/iocsr_helper.c | 16 +-- 9 files changed, 195 insertions(+), 155 deletions(-) base-commit: 9c74490bff6c8886a922008d0c9ce6cae70dd17e -- 2.39.3
